Your challenge, should you choose to accept it, involves building a storage service. The storage server is meant to store arbitrary data. You are to build a REST API (HTTP/1.1, or 2.0, your choice) that presents a data storage, and retrieval API.
Your environment runs on Ubuntu 16.04 in a Docker container as a non-root user. You are allowed to write to the current working directory.
You are to build your deliverable so that it extracts into the following layout:
| SET client_min_messages TO NOTICE; | |
| SELECT hll_set_output_version(1); | |
| DROP TABLE IF EXISTS test_valgrind; | |
| CREATE TABLE test_valgrind (id integer, set hll(11, 5, -1, 1)); | |
| INSERT INTO test_valgrind(id, set) VALUES (1, hll_empty()); |

| ) | |
| func dup(oldFile *os.File, flag int) (int, error) { | |
| // Temporary file descriptor for /dev/null. | |
| devNull, err := os.OpenFile(os.DevNull, flag, 0) |
